* Update code dependencies
I also wanted to update logback, but I'm hitting issues because of our
custom logger in `FixtureSpec` (`LoggingEventAware` not found).
* Update build dependencies
We're now using mvn 3.9.2 to build eclair, which reports warnings in some
of the build plugins we use. Updating plugins fixes most of the warnings,
and the remaining warnings have to be fixed by the plugins themselves
to support mvn 4.x.
This release of bitcoind contains several bug fixes that let us simplify
our fee bumping logic:
- fixed a bug where bitcoind dropped non-wallet signatures
- added an option to fund transactions containing non-wallet inputs
It also has support for Taproot, which we want in eclair.
This PR does two main things:
- introduce a new `FixtureSpec` base class for tests that involve a fixture. See the scaladoc for more info.
- add new simple integration tests in package `integration.basic`. They are based on `MinimalNodeFixture`, which is a full setup for a node with real actors, except the bitcoin part (watcher/wallet) which is mocked. They are much lighter than our previous integration tests, which allow us to keep each test individual, as opposed to having all tests of the same suite depend on each other. We can define more complex fixtures with any number of nodes.
Other minor improvements:
- update scalatest version
- simplify `ChannelStateTestsHelperMethods`
- replace all === by ==
Triple equals allows customizing the equality method, but we never use
that.
Detailed errors (which is what we were looking for) are provided by
mixing in scalatest's `Assertions` and using the regular `assert(x==y)`
syntax. The `Assertions` trait is already mixed in by default in all
scalatest suites.
In this PR we add a basic integration test between `Channel` and `Router` that checks the proper handling of local announcements.
* disable router rebroadcast in tests
* use separate ActorSystem for alice and bob in tests
* add a simple channel-router integration test
* fix bug found in new channel-router test
The new test was failing, due to a bug. When a local
channel graduates from private to public, we do not copy existing
known `channel_update`s. Current implementation guarantees that we
will process our local `channel_update` immediately, but what about our
peer?
* fix rebroadcast for local announcements
We fix a second bug where gossip origin wasn't properly set for local
announcements
* increase ram for tests to 2G
* improve debuggability of integration tests
We use a version of bitcoin-lib that uses bitcon-kmp under the hood.
Its API is the same as before, but its package is now fr.acinq.bitcoin.scalacompat
* use `NodeAddress` everywhere instead of `InetAddress`
This makes us control more strictly when and where name resolution happens, which is important in a security-hardened setup. The `InetAddress` jdk class indeed does a lot of things behind the scenes, but now we restrict it to tcp-related classes like `Client` and `Server`.
Also, in _cluster mode_ all outgoing connections (including tor) are now made on the front.
* upgrade guava and rewrite nodeuri tests
There is no reason to use the version of guava targetting android anymore. Also `HostAndPort` was in beta in our current lib version.
We now use guava's `InetAddresses.toUriString()` to format host string, instead of manually adding brackets.
Reworked `NodeURI` tests:
- less repetition with one single test and multiple `testCases`
- focus on non-reg (no need to verify what we know we don't support)
There are no functional changes, but bitcoin-lib 0.19 is based on secp256k1-kmp (instead of our own fork of secp256k1's JNI wrapper) which is cleaner, easier to maintain and used in our mobile apps.
From scalatest's doc [1]:
> This minimizes or eliminates the need to search and scroll backwards
to find out what tests failed or were canceled. For large test suites,
the actual failure message could have scrolled off the top of the
buffer, making it otherwise impossible to see what failed.
